Time Reverse Equalization Algorithm for 16 QAM Coherent Optical Communication Systems
IEEE Access, 2021 The high speed rotation of state of polarization (RSOP) is a key issue for 16 quadrature amplitude modulation (QAM) coherent optical polarization division multiplexing (PDM) communication systems in strong lightning weather. To reduce the bit error rate (

Information gap for classical and quantum communication in a Schwarzschild spacetime [PDF]
, 2012 Communication between a free-falling observer and an observer hovering above the Schwarzschild horizon of a black hole suffers from Unruh-Hawking noise, which degrades communication channels. Ignoring time dilation, which affects all channels equally, we

Binary Communication with Gazeau–Klauder Coherent States
Entropy, 2020 We investigate advantages and disadvantages of using Gazeau−Klauder coherent states for optical communication. In this short paper we show that using an alphabet consisting of coherent Gazeau−Klauder states related to a Kerr-type nonlinear ...
